Apple CEO Tim Cook told TheWall Street Journal on Thursday that users will soon be able to receive e-mail notifications when iCloud data is restored. Apple already sends e-mails to users when a new password is requested, when a password is changed, or when an account is used on a new device for the first time.

The company will start to send out the new notifications in two weeks, according to the WSJ. It will also expand the two-step verification process—which requires a separate code or a key in order to log in to an account—to include access to an iCloud account on the new iOS.

In an interview with the WSJ, Cook acknowledged that Apple could have done more to prevent the attack on female celebrities' accounts.

"When I step back from this terrible scenario that happened and say what more could we have done, I think about the awareness piece," he told the publication. "I think we have a responsibility to ratchet that up. That's not really an engineering thing."

Cook said that the hackers accessed the women's accounts by obtaining their usernames and passwords in a phishing scam or by guessing security questions to obtain their passwords.
